SPECIFICATION forming part of Letters Patent No. 276,115, dated April 17, 1883.

Application filed January 5, 1883. (No model.) Patented inEnglnnd November 17, 1880, No, 1,732

T0 all whom it may concern:

Be it known that we, THOMAS WILLIAMS, Jr., and WILLIAM SANGSTER, citizens ct' England, residing, respectively, at Gee Street,

5 Goswell Road, and at Compton Buildings,

Goswell Road, both in the county of Middlesex, England, engineers, have invented new and useful improvements iu machinery or apparatus for forcing sausage-meat and other substances into skins or other suitable receptacles,(for which we have obtained a patent iu Great Britain, No. 4,732, bearing date Novemher 17, 1880,) of which the following is a specitication.

Our said invention relates to the class of' sausage-filling machines wherein a cylinder and a piston or plunger working therein are employed for forcing the meat or other substance into skins or other receptacles; and it `consists in the combination, with such machines, of the peculiar arrangement of driving-gear hereinafter described, whereby the piston or plunger is caused to move slowly while forcing out or expelling the contents of the cylinder, and to return by a quick inotion to the rear or open end ofthe cylinder so soon as it has completed its forward traverse, and vice versa, the reversing of its motion'and the corresponding change of speed being ef- 3o fected automatically or otherwise at the end of each single stroke ofthe piston.

The improved machine is by preference arranged so as to be driven by power; but,it' desired, it may be worked by hand through the same arrangement of gearing.

`vAnd in order that our said invention may be fully understood,we shall now proceed more particularly to describe the saine, and for that purpose shall referto the several ligures on the explanatory sheet ot' drawings hereunto annexed, the same letters of reference indieating corresponding parts throughout all the figures.

Figure 1 of our drawings is a sido elevation of our improved filling-machine arranged so as to be self-acting and driven by power. Fig. 2 is a corresponding plan ofthe same. Fig. 3 is an end elevation corresponding to Fig. 1, and looking on the driving end of the machine;

| and Figs. el, 5, 6, and 7 are details of the drivo ing-gear combined with the said machine for producing the alternate quick and slow inotions ofthe piston or plunger.

A is the bed or base plate of the machine, provided with side standards, B B, for supporting the filling-cylinder G, which is provided with the usual nozzle, D, for receiving the sausage-skin 0r other receptacle. This cylinder is supported on trunnions E E at its front or delivery end, which rest in suitable bea-rings in the top ofthe side standards.

F F are stops for supporting the cylinder iu its horizontal or working position, as shown in the drawings, which stops, when the cylinder is in its working position, take their bearing upon the upper edge of the standards B.

G is the piston or plunger working inside the cylinder, as is well understood, and connected with a rack, H, supported and guided by the bearings I, through which itslidesfreely.

K is the driving-shaft, supported at one end in the bearing L, while its opposite end is supported by and turns freely in a recess, n, in the end of the short shaft M,which shal'tworks 'iuvbearings N N andv carries a spur-pinion, lWI, in gear with the rack H. (Shown more clearly in dotted lines in Fig. 2.) One end ofthis shaft M is shown in detail section at Fig. 7.

O is the fast driving-pulley, keyed onto the first-motion shaft K.

P is au ordinary loose pulley on the same shaft, and Q is a second loose pulley,which is formed with internal teeth, as hereinafter explained, and serves also as a brake-pulley for the reception of the brake-strap R, worked by the hand or foot lever S. l

b is an intermediate spur-wheel mounted upon an eccentric, c, on the driving-shaft K, and gearing into the internal teeth, q', formed inside the loose driving-pulley Q, as shown clearly in the details, Figs. l.tand 5. This intermediate spur-wheel, b, acts as a carrier-A wheel, aud is made sufficiently broad to engage at the same time with the teeth t of`the internal-toothed wheel T, fast ou the'end of 95 the shaft or spindle M. (See Fig. 2 and details, Figs. 6 and 7.)

We do not confine or restrict ourselves to the precise number or proportions of teeth shown in our drawingsin the before-mentioned arrangement of driving-gear, as the proportions may be varied; but those shown will be found to giv'e a good result-namely, say ten teeth in the intermediate spur-wheel, 1),.thirteen teeth in the loose internal-toothed brakepulley Q, and twelve teeth in the internaltoothed wheel T.

U is a sliding rod (which may be used when the machine is to work automatically) sliding in suitable guides, and connected by a stud or pin, V, or otherwise, with a slot in the end of one of the arms of the horizontal bell-crank lever W, the other arm being connected, as shown clearly in Fig. 3, by a similar stud or piu, or its equivalent, with a horizontal slide, X, working in guides Y. Through a slot in this'slide passes the upright weighted lever or strap-shifter Z, carrying the fork or strapguide d.

y In commencing to work the machine the cylinder is first charged with meat or other substance, the driving-strap being outhe pulley O. The attendant then applies the brake R, whereupon a slow motion is transmitted vfrom the fast pulley O, through the shaft K,

intermediate spur-wheel, b, internal stationary toothed pulley Q, and internal-toothed wheel T, to the shaft M and spur-pinion M.` The rack H and piston Gr will then commence to` move slowly inward, the speed of the spur-pinion M being-reduced to about one revolution to twelve of the driving-shaft K, as thc intermediate spur-wheel, b, on the eccentric-c is caused to travel or gyrate round the circle ot' internal teeth in the pulley Q and internal-toothed wheel T simultaneously, and also to revolve round the said rotating eccentric, but in a reverse direction to that of the eccentric and shaft K. Just before the piston has arrived at the front or delivery end of the cylinder the arm ve on the end of the rack H pushes the sliding rod U inward, thereby moving the bellf crank W, slide X, and ylever Z into the reverse position to that shown in Fig. 2, and consequently shifting the driving-strap from oil'1 the driving-pulley O onto theloose internal-toothed pulley Q, the brake-strap on the said pulley being at the same time released by the attendant, so as to allow the pulley Q to rotate freely, while the shaft K may remain stationary. AA

Aquick rotary motion (in the reverse direction to that previously obtained) is by this adjustment transmitted from the internal-toothedV pulley Q, through the intermediate spur-wheel, b, direct to the internal-toothed wheel T, fast on the shaft M, which carries the spur-pinion M', the intermediate spur-wheel, b, revolving freely round the eccentric c as a center and serving as a carrier-wheel. The result is a quick return motion of the rack H and piston Just as the piston is emerging from the rear or open end ofthe cylinder it pushes 'the rod U outward, and brings the bell-crank lever W and slide X, with the weighted strapshifting lever Z, into the positions shown in Figs. 2 and 3, thereby shifting the drivingstrap by the action of the fork d from the loose pulley Q, back again onto the fast driving-pulley O. The slow forward motion of the piston or plunger G can be instantly arrested at any moment by simply releasing the brake R.v A lcver-arm,f, actuated by the upright handle g, serves to turn up the mouth of the cylinder into the position shown by dotted lines in Fig. l, for the purpose ot' facilitating the introduction of a further charge of sausagemeat or other substance therein, after which the cylinder is lowered to its original horizontal position and the machine is started again.

The trunnions E E and their bearings are by preference so shaped as to constitute stops for preventing the cylinder from being aceid'entally turned beyond a vertical position.

What we claim, and desire to'secure byLetters Patent of the United States, is

1. The combination of the shaft provided with thetixed internally-toothed wheel, the shaft provided with the eccentric and theloose internally toothed, pulley, the spur wheel mounted on the eccentric and meshing with the toothed pulley and wheel, a brakestrap foralternately holding thetoothed pulley fixed and then permitting it to turn, and means for imparting motion to the shafts, whereby the several parts will operate substantially as set forth.

2. In a sausage-filling machine, the combination of cylinder C, mounted ou trunnions, and piston G, carrying the rack H, with the short shaft M, carrying the spur-wheel M', and internal-tootl'ied wheel T, the tirstmotion shaft K, carrying the driving-pulley O, internal-toothed brake-pulley Q, and intermediate spur-wheel, b, mounted on the eccentrico, the brake-strap B., and the lever S, all substantially as specified.

3. The two shafts provided with the internally-toothed wheel and pulleymeshing with the spur-wheel mounted on the eccentric, in combination with the piston-rack provided with an arm, the rod and the slide connected by the bell-crank lever, and the belt-shifter 'acted on by the slide, the several parts being arranged to operate as set forth.

In witness whereof we have signed our names in the presence of two subscribing witnesses. Y
